FIRE-EXTINGUISHEB.

Specification of Letters Patent. 7

Application filed July 12, 1916. Serial No. 108,803.

To all whom it may concern:

Be it known that 1, JOHN W. FITZGERALD, a citizen of the United Statesof America, residin at Detroit, in the county of of Wayne and btate ofMichigan, have invented certain new and useful Improvements in Fire-Extinguishers, of which the following is a specification, referencebeing had therein to the accompanying drawings.

The invention relates to fire extinguishers of that type in which afluid is stored within a container provided with manually-operableejecting means. It is usual to provide such devices with a plunger pumpfor ejecting the fluid, but there is always danger that when there isoccasion for use the pump may not be in operative condition;furthermore, to form the pump or ejector, a cylinder provided with aclosely-fitting or packed piston is required, which materially increasesthe cost of the construction. It is the object of the present inventionto simplify the construction, to insure operativeness of the same at alltimes and to maintain the fluid sealed until used. This I haveaccomplished by the use of a collapsible tube container for the fluid,in combination with manually-operable means for collapsing the tube toeject the fluid when required.

In the drawings:

Figure 1 is a perspective view, showing one construction of my fireextinguisher;

Fig. 2 is a section, showing the retaining cap for the tube;

Fig. 3 is a cross section.

A is a collapsible tube formed of soft metal, being closed and sealed atone end, and provided at its opposite end with a discharge nozzle B,'Wltll a suitable closure such as a cork C and removable cap D. E is acollapsing device for the tube, which, as shown in Fig. 1, comprises apair of side members embracing the tube and hinged to each other at F,thev nozzle B projecting through an opening between the hinges. Theopposite ends of these members form handles for grasping to squeeze thetube and to eject the fluid contents therefrom. Each of the members E isprovided. with a pair of side flanges E, said flanges of one of saidmembers being adapted to telescopically engage those of the other duringcolla sing of the tube. An end bearing portion for the tube ispreferably provided, which,-as shown, is struck out from one of themembers and is adapted to pass through an aperture H in the oppositemember.

With the constructions above described, when the extinguisher isrequired for use, the cap is removed and the tube collapsed to eject thefluid contents through the nozzle.

'l/Vhat I claim as my invention is:

1. A fire extinguisher, comprising a collapsible tube containing theextinguishing fluid and provided with a discharge nozzle, means forsqueezing said tube forming a container therefor, comprising two'membersembracing opposite sides of the tube, hinged to each other and flangedto telescopically engage each other as the tube is collapsed betweensaid members, the ends of said members being prolonged to form operatinghandles, and a bearing for supporting the bottom of. the collapsibletube projecting laterally from one of said members.

2. A fire extinguisher, comprising a collapsible tube containing theextinguishing fluid and having a nozzle for discharging the fluid, meansfor squeezing said tube, comprising a pair of members hinged to eachother at one end and centrally cut away Patented (Oct. e, rat a; I

for the passage of the nozzle, said members embracing the opposite sidesof the tube and being flanged to telescopically engage each other as thetube iscollapsed between said members, operating handles formed byprojecting the ends of said members, and a support for the bottom of thetube struck out from one of said members to project laterally therefrom.

3. A fire extinguisher, comprising a collapsible tube containing theextinguishing fluid and provided with a discharge nozzle, means forsqueezing said tube comprising a pair of members hinged to each other atone end and cut away for the passage of said nozzle, said members beingconcaved to embrace opposite sides of the tube and to telescopicallyengage each other, a support for the bottom of the tube struck out fromone of said members, the opposite member being apertured to receive saidstruck-out portion during the collapsing of the tube.

4. A fire extinguisher, comprising a collapsible tube containing theextinguishing fluid, and means for squeezing the fluid therefrom,comprising a pair of members hinged to each other and embracing theopposite sides of said tube, said members being flanged totelescopically engage each other as the tube is collapsed between thesame and being extended to form operating handles.

5. A fire extinguisher, comprising a col-' handles and havin ortionsretainin the container against displacement in a direction parallel tothe hinge axis.

U. A lire extinguisher, comprising a collapsible container for anextinguishing fluid, and means for squeezing said container to eject thefluid therefrom comprising a pair of members hinged to each other andembracing opposite sides of said container, said members being extendedto form handle.

memes lapsible container for the extinguishingfluid, and means forsqueezing said container to eject the fluid comprising a pair of membershinged to each other and embracing 0pposite sides of said container,said members being extended to form handle portions, one of said membershaving a tongue struck out forming an' abutment preventing expansion ordisplacement of the container into the space betvveen the handleportions, and the 4 other member being slotted to allow passage of saidtongue.

Intestimony whereof I aflix my signature.

JOHN W. FITZGERALD.
